[BUTTOBE, A Training Program for Future Medical Innovators, Has Been Proposed as an Advanced Doctoral Program at the Tokyo University of Pharmacy and Life Sciences].

To overcome the decline in the number of students advancing to doctor of philosophy (PhD) courses in graduate schools in Japan, the government of Japan launched a new five-year program in 2021: Support for Pioneering Research Initiated by the Next Generation (SPRING). SPRING is overseen by the Japan Science and Technology Agency (JST) as an integrated program that provides outstanding PhD course students financial support in an amount equivalent to their living expenses and research expenses, as well as career development and human development courses and support. The proposed advanced doctoral program for medical innovators at Tokyo University of Pharmacy and Life Sciences was selected for SPRING support under the theme of "Beef Up Toyaku talents TO go BEyond the borders" (BUTTOBE). This report describes the purpose and current activities of the BUTTOBE program.
